Touch Screen interface with TMS320F28069

Other Parts Discussed in Thread: TMS320F28069

I need to interface a  Touch Screen display ( say 6 X 4 inch ) to my TMS320F28069 system.
I plan to use the Launchpad board to speed up development.
Please point me to some Tech Note by Texas Instruments that would give step-by-step details along with source code on interfacing a Touch Screen.

My expectation is that there are Touch Screens with built in controllers and a user's guide that will provide information on data structures for reading/writing data over say a I2C channel.
I want to avoid having to scan the Touch Screen over the ADC ports and calculating the XY touch points myself and also drawing stuff on the screen by some vector or raster commands.

Forgive my ignorance, I work on Analog systems with physical push-buttons, potentiometers, meters and this is my first project to develop digital equivalents of the systems.

If TI recommends a TouchScreen, I will purchase it - provided full details for interfacing with TMS320F28069 are provided.

    Hi Nereus,

    Please point me to some Tech Note by Texas Instruments that would give step-by-step details along with source code on interfacing a Touch Screen.

    C2000 controllers have no display drivers available be it any display. You need to create your own drivers or use a Serial Display that supports SCI, I2C or SPI.

    Regards,
